EVAL-AD5313RDBZ User Guide
Alternatively, the EVAL-AD5313RDBZ
be used without an evaluation board. The
evaluation software runs in simulation mode displaying
expected outputs based on the input data. The main window of
the EVAL-AD5313RDBZ evaluation software then opens, as
shown in Figure 4.

SOFTWARE OPERATION

The EVAL-AD5313RDBZ evaluation software allows the user to
program values to the input and DAC registers of each DAC
individually or collectively.
Write to Input Register
Click the Write to Input Register button to load the code of the
input data control to the input register of the selected DAC
(DAC A, DAC B, or All DACs).
Update DAC Register from Input Register
Click the Update DAC Register from Input Register button to
copy the value in the input register to the corresponding DAC
register. DAC outputs are automatically updated with the
appropriated voltage. Ignore the LDAC MASK indicator LED.
Write to Input and DAC Registers
Click the Write to Input and DAC Registers button to load the
code of the input data control to the input register and DAC
register of the selected DAC. The DAC outputs are automatically
updated with the appropriated voltage. Ignore the LDAC MASK
indicator LED.

LDAC Control
Select the Pulse LDAC button to bring the LDAC pin low and
then back to high, copying the data from the input registers to
the DAC registers, and the outputs update accordingly. Ignore
any DAC updates disabled by the LDAC mask settings.
The LDAC pin can also be set high or low by clicking LDAC
HIGH or LDAC LOW, respectively.
LDAC Mask Register
Each DAC can be configured to respond or ignore the LDAC
pin settings in the LDAC Control. Click the blue progressive
disclosure option on the LOGIC INTERFACE block to access
the LDAC Configuration window, as shown in Figure 5.
When the LDAC selections are completed, click OK to write the
appropriate values to the AD5313R. The LDAC MASK indicator
LED lights up accordingly when a DAC LDAC mask is enabled.
